FORCEPS.

SPECIFICATION forming part of Letters Patent No. 686,578, dated November12, 1901.

Application 'filed March 26, 1901. Serial No. 52,937. (No model.)

To all whom it may conccrm.

Be it known that I, DAVID FREDERICK Bow- ERSOX, a citizen of the UnitedStates, and a resident of Aaronsburg, in the county of Center and Stateof Pennsylvania, have invented new and useful Improvements in Forceps,of which the following is a full, clear, and exact description. c

This invention relates to forceps designed especially for veterinary usein performing operations in the esophagus of animals. It embodiescertain features of construction by which I am enabled effectively andeasily to perform this work without in any way endangering the animal bylaceration.

This specification is a specific description of one form of theinvention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a side View of my invention with device, and Fig. 3 is asimilar view of theinner portion.

0. indicates the jaws of the apparatus which may, if desired, beserrated on their inner faces and which have their points turned inwardto more efiectively engage the object to be removed. These jaws arepivoted within a cavity 12, formed in a holder b, the pivots and theinner ends of the jaws being so arranged that it will be impossible tolacerate the throat of an animal by the movement of the jaws. A spring 0is employed to spread the jaws normally apart, and the jaws have atoggle a connected thereto, by which they may be moved together throughthe medium of other devices which will be hereinafter described.

The stock of the forceps may be of any length suitable to the nature ofthe work to be performed. It is formed of a flexible structure made upof an exterior casing 01, preferably of leather, within which isarranged a coil-spring d. The jaw-holder'b is arranged at the outer endof the stock and has a tubular extension 6 projected thereinto. At theinner end of the stock (see Fig. 3) the stock has a terminal block (1with which the spring d and exterior casing d are engaged. This block (1has a tubular extension 61 projecting 'into the stock, and between thesetwo tubu lar extensions 6 and d longitudinally-extending wires (1 arepassed, such wires serving to hold together the parts of the stock andto make up the flexible structure thereof.

6 represents the handle of the apparatus, which may be of any formdesired. This handle is constructed with a cavity e therein, in which isarranged the part f of the operating-lever f. This operating-lever lieson the outside of the handle and is movable, as indicated by the dottedlines in Fig. 3. Connected with the part f of the lever f is a couplingf to which a wire f is connected, and this wire passes completelythrough the stock and is joined to a coupling 1, connected in turn withthe toggle e. The spring a normally throws the jaws open and causes thelever f to assume the position shown in I Fig. 3. By pressing the leverf toward the handle a the toggle a may be broken and the jaws a forcedtogether, as shown by dotted lines in Fig. 2. V

In using the device the lever f may be depressed to close the jaws, andthen the forceps may be inserted into the passage in which the operationis to be performed. When the forceps have been placed in the properposition, the spring 0 will be operated to open the jaws, and then uponagain operating the lever f the jaws may be closed into active position.

The uses and advantages of my invention will be apparent to personsskilled in the art, and further comment on these parts will not benecessary.

Various changes in the form, proportions, and minor details may beresorted to without departing from the spirit and scope of my invention.Hence I consider myself entitled to all such variations as may liewithin the scope of my claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- l.
